Salinity effects

Highly abundant in areas of 0.0 - >25 ppt in the Matagorda Bay only. In other Texas bays, these shrimp have regions of high abundance in the 0.5 - 35 ppt. Associated with high abundance of vegetation or oysters.

Gray snapper are euryhaline, and have been observed in salinities between 0.0 ppt and 67.0 ppt.

Non-gravid, developing adults thrive in salinities of approximately 20-25 ppt. Postlarval and juvenile menhaden prefer salinities of anywhere between 5-30 ppt. However, a study was done in 2005 that concluded Gulf menhaden in the Sabine Estuary in Texas, USA preferred salinities between 3-6 ppt.

Gulf menhaden are most abundant in regions of <15 ppt and regions of 18-23 ppt.

Preferred salinity was shown to be between 0-12 ppt for both adults and juveniles.
